In this video review, Dr. Rohit S. Loomba discusses the normal cardiac anatomy and morphology of the neonatal heart, using a high-fidelity heart specimen to provide a detailed, three-dimensional walkthrough. He begins by orienting the viewer to the anatomical position of the heart within the thorax, then sequentially opens each chamber to highlight key internal structures. Starting with the right atrium, Dr. Loomba identifies the right atrial appendage, pectinate muscles, oval fossa, and the coronary sinus guarded by the Thebesian valve. He then describes the tricuspid valve, noting its septal leaflet attachment, which distinguishes it as morphologically right-sided. The right ventricle is characterized by coarse trabeculations and the presence of the septomarginal trabeculation (moderator band)—both hallmark features of right ventricular morphology. Next, he examines the pulmonary valve, demonstrating its three cusps and the muscular support typical of this structure. Dr. Loomba also emphasizes the misconception of a circular valvular annulus, explaining instead the crown-shaped anatomy of the semilunar valves. Transitioning to the left side, Dr. Loomba highlights the left atrial appendage, noting its smaller, smoother structure and absence of pectinate muscle extension beyond the appendage, consistent with left atrial morphology. He reviews the mitral valve, with two leaflets and no septal attachments, and demonstrates the smooth-walled left ventricle. He concludes by discussing the aortic valve, its three leaflets and coronary artery origin, and the continuity between the aortic and mitral valves via the fibrous aortomitral curtain, distinguishing it from the fully muscular support of the pulmonary valve. This video provides an essential foundation for learners in pediatric cardiology, cardiac morphology, and congenital heart disease.
